Vivarium for Terrantula (Watford WD18)

Hi All,I have a male chilean roseback terrantula but he has a small plastic ventillated box for a home but im sure this is not enough space for him.Therefore ideally i am looking for a vivarium or medium sized fish tank style home that will enable him to live life to the full when not out of his box.If anybody has one they no longer require I would be everso grateful to receive one. I can collect if necessary
